The clinical significance of CEA and circulatory NETs in CRC patients A The CEA levels in the serum from HCs (n = 56), CRP patients (n = 29) and CRC patients (n = 95). B Correlation between serum CEA levels and NETs levels in CRC patients. C ROC curve of serum CEA levels, NETs levels, and CEA combined with NETs levels for identifying CRC patients from HCs. D ROC curve of serum CEA levels, NETs levels, and CEA combined with NETs levels for identifying CRC patients from CRP patients. E ROC curve of serum CEA levels, NETs levels, and CEA combined with NETs levels for identifying metastasis in CRC patients. **p < 0.01, ***p < 0.001
